Why do we loathe certain actors? It's really hard to say. Some we deem to be ungifted hacks. Others taint god-given talent with their own personal train wreckish lifestyle. (In the biz they call it "Lohaning.") Whatever it may be, there is a certain point when we, the moviegoer, are ready to write off an individual. But maybe we shouldn't be so hasty. Fame is a bumpy ride, after all, and the person who we rip from the pages of "Tiger Beat" today, may one day make us burn in shame. Similarly, the people we deem mock worthy failures may one day surprise us. Yes, Tara Reid, January Jones, it's not too late for you. You can still make a comeback. These 10 certainly have. Because everyone deserves a chance to make a comeback. Everyone but Charlie Sheen.
